Deleting Values in Qualified Table

We need to delete values in a QT.

Some of them are already associated with a record in a main table and can not be deleted from teh QT directly.

Uisng teh Data Manager, we can select the records, then the values in the QT, right click and choose remove to delete the QT value for that particular record.

Instead of doing one by one, Is there a way to do the same for a large number of records?

Thanks
